## Assertr Description
You know what you want to say. You've rehearsed it in your head a hundred times. But when you're in the room - your mind goes blank.

Assertr is an AI voice coach that lets you practise difficult conversations out loud before they happen. Not typing. Speaking. The way real conversations actually work.

WHAT YOU CAN PRACTISE:
- Salary negotiation - 57% of workers never ask. 2/3 who do, get the raise
- Tough feedback - be honest without burning bridges
- Job interviews - answer hard questions under pressure
- Speaking up in meetings - stop being the quiet one
- Difficult boss conversations - navigate what you've been avoiding
- Setting boundaries - say no without guilt
- Team conflict - resolve disputes with clarity
- Offer negotiation - maximise your compensation

WHY VOICE, NOT TEXT:
You already know ChatGPT can role-play in text. But real conversations aren't text. They're voice, pressure, emotions, and someone going off your carefully prepared script.

Assertr puts you in the conversation. Out loud. So when the stakes are real - you've already been there.

HOW IT WORKS:
1. Pick a scenario or describe your own
2. Have the conversation out loud with AI
3. Get scored on 5 dimensions: clarity, confidence, empathy, assertiveness, strategy
4. See exactly where you went off track
5. Practise again until you're ready

THE MATHS:
One successful salary conversation = GBP 4,000-GBP 12,000/year.
One Assertr session = 10 minutes.
You already spend hours overthinking it. Spend 10 minutes practising instead.

BUILT FOR THE NIGHT BEFORE:
Got a performance review tomorrow? A tough conversation you keep postponing? Assertr is available at 11pm - when the anxiety peaks and a human coach isn't.

Track your growth across sessions. Build real communication skills. Turn deep conversations into career breakthroughs.

Stop overthinking. Start practising.
